The external intercostal muscle contrast and elevating, the internal intercostal muscles relax, raising the ribs upwards and outwards. 
2. At the same time, the diaphragm contraction of the thoracic cavity.
3. All of these actions increasing the chest volume, that cause different pressure between inside and outside. The air pressure in lungs lower than pressure of atmospheric.
4. The greater atmospheric pressure push the air into lungs through your nose or mouth,then to lungs.
5. This process will make alveoli get enough air to meet oxygen demands of tissue.]]> 2017-03-16 01:32:57 UTC https://padlet.com/787453250/z12v97odbppn/wish/160408528 Expiration 787453250 https://padlet.com/787453250/z12v97odbppn/wish/160408559 1.     The external intercostal muscle relaxes, the internal intercostal muscle contrast.
2.     This process lead to ribs move to downwards and inwards.
3.     At the same time the diaphragm relaxes to upwards.
4.     Thoracic cavity volume decrease
5.     Elastic lungs recoil passively; intrapulmonary volume decreases, so the air pressure in lungs increase to above atmospheric pressure, then air flows out of lungs down its pressure gradient.

  • Exchange of oxygen and carbon dioxide between the respiratory system and the circulatory system.
  • Gas exchange occurs at the alveolar sacs which are lined with capillaries.
  • Oxygen diffuses from the alveoli into the capillary and is transported by the iron-rich protein Hemoglobin.
  • Carbon Dioxide, as waste, is returned to the alveoli by binding itself to the Hemoglobin in the capillaries. It then diffuses out of the blood and into the alveolar sacs.
  • Release energy

  • Exchange of gases between the Circulatory System and the cells.
  • Hemoglobin transports oxygen to the cells through the capillaries. It also picks up carbon dioxide wastes from the cells.
